Currently, attempts are made to develop hardfacing cobalt-free alloys for coating the contact areas of moving parts of nuclear installations. In fact, under neutron flux, cobalt 59 is activated into cobalt 60, a highly radioactive isotope. Consequently, the coating debris generated by friction are likely to contaminate parts of the installation. Existing cobalt-free hardfacing alloys, nickel or iron bases, do not exhibit tribological properties competing with those of stellite®, a commonly used hardfacing cobalt base alloy. HEA (High Entropy Alloy) and CCA (Complex Concentration Alloy) may be good candidates. Indeed, compare to conventional alloys, they show vast composition domain giving access to a large range of properties. After an init...
